The vertical plate 3 is longitudinally arranged on the inner side of the lower end of the fume collecting hood 1; the upper end of the curved plate 2 is close to the middle part of the fume collecting hood 1 and has a gap with the lower end surface of the fume collecting hood 1, the lower end is connected with the vertical plate 3, and the side surface of the lower end of the curved plate 2 is provided with a second air inlet 21; the side plates 4 are two sides respectively arranged on the vertical plate 3 and the curved plate 2, and form a smoke collecting cavity together with the vertical plate 3 and the curved plate 2.
The rectifying plate 5 comprises a flat part 52 and a curved surface part 51 extending downwards from the inner side of the flat part 52, the flat part 52 is arranged close to the bottom of the fume collecting hood 1 and forms a fume collecting channel with the lower end surface of the fume collecting hood 1, and the curved surface part 51 is arranged on the outer side of the curved plate 2 and also forms a fume collecting channel with the outer side surface of the curved plate 2; the corners of the rectifying plate 5 are rounded. The inner side of the lower end of the rectifying plate 5 is turned to form an oil collecting groove 53.
The oil cup 6 is arranged at the lower end of the curved plate 2 and is used for receiving oil flowing down from the outer side surface of the curved plate 2 and the smoke collecting cavity.
The curved surface plate 2 includes an arc section 23 located inside the curved surface portion 51 and a flat section 24 extending downward from the arc section 23, and correspondingly, the curved surface portion 51 is arc-shaped and the arc is consistent with the arc section 23. The flat section 24 is provided with a second air inlet 21, and the circular arc section 23 is provided with a third air inlet 22.
The second air inlet and the third air inlet in the embodiment are long and narrow, and have flanging, so that the oil can be filtered.

The whole machine is provided with a first air inlet above, a second air inlet below and a third air inlet in the middle, the second air inlet can draw in cooking fume at first time, the middle part forms side air inlet in the left-right lower three directions by the rectifying plate and the side wall of the curved plate, the side air inlet enters the machine body through the third air inlet, and the top part forms the first air inlets in the left-right front three directions by the rectifying plate and the fume collecting hood, so that the fume collecting range is wider and is closer to the cooking bench; the rectifying plate and the curved plate are both in curved surface shapes, so that the wall attaching effect is effectively utilized to adsorb oil smoke, and the rounded corners at the four corners of the rectifying plate have the same flow guiding effect and reduce vortex; the accelerating channel formed by the rectifying plate and the curved plate enables the oil smoke to be sucked away more quickly.
As shown in fig. 3, after the blower is started, the cooking fume generated by cooking is sucked into the kitchen ventilator in two paths as a whole. The first path is as follows: the oil smoke close to the curved plate 2 is drawn in by the second air inlet, a small amount of oil smoke enters the smoke ventilator through the second air inlet, the rest of oil smoke rises along the curved surface under the action of the wall attaching effect, when the oil smoke reaches the vicinity of the side air inlet, the oil smoke close to the inlet is sucked into the accelerating channel and then enters the smoke ventilator through the third air inlet, and the rest of oil smoke enters the first air inlet under the wall attaching effect of the rectifying plate; the second path: and after the fume which is far away from the side wall naturally rises to the arc-shaped rectifying plate, the fume rises along the arc-shaped surface under the wall attaching effect of the rectifying plate, and enters the range hood from a third air inlet formed by the rectifying plate and the fume collecting cavity.
The separated oil mainly flows to two places: most of the oil flows downwards along the curved plate and flows into the oil cup at the bottom through the oil leakage hole of the bottom plate; a small part of the oil enters the oil groove below the rectifying plate, and the oil groove can be integrally formed with the rectifying plate and can be independently provided with an oil cup.
In embodiment 2, the curved plate in this embodiment does not have a third air inlet, so that the oil smoke entering from the side air inlet enters the machine body directly from the first air inlet at the lower end of the fume collecting hood after entering the accelerating channel. One-time oil smoke filtering effect is lacked. Other structures refer to embodiment 1.
